Source: Geometry Wars 2 announced tomorrow, dropping this week?

A reliable source close to Joystiq informed us that Geometry Wars 2 will be announced at Microsoft's press conference tomorrow morning. That wouldn't be much of a surprise -- after all, the achievements were leaked on Xbox.com two weeks ago.

Our source informs us that the game has already passed certification, clearing the major barrier of entry for all Xbox Live Arcade titles. Is Microsoft going to "bring Geometry Wars 2 home" tomorrow? We already know they're launching Coffeetime Crosswords and Shred Nebula next week, but a follow-up to Xbox 360's Number 1 launch title would be polygonal icing on the keynote cake.
